Definitions

  • the present invention relates to an image processing apparatus, a method and a program, and an ink jet recording apparatus, and more particularly, to a technique for correcting streaks due to defective nozzles of an ink jet head.
  • the gamma conversion processing at a resolution lower than the recording resolution of the ink jet head and the gamma conversion processing at the recording resolution of the ink jet head can be performed, so that the density can be appropriately flattened. Furthermore, it can be appropriately quantized into output data represented by ink droplets of a plurality of sizes.
  • FIG. 1 is a schematic diagram of an inkjet recording apparatus 1 according to the present embodiment.
  • an inkjet recording apparatus 1 is a single-pass line printer that forms an image on a recording surface 2A of a recording medium (paper) 2.
  • an inkjet head 3 for recording an image on the paper 2.
  • Magenta ink (M ink), black ink (K ink), cyan ink (C ink), cyan ink (C ink), respectively, on the surface of the four line heads 120M, 120K, 120C, 120Y (an example of an inkjet head) facing the conveyance drum 110, respectively.
  • a plurality of nozzles for discharging yellow ink (Y ink) are formed over the entire width of the paper P.
  • the line head 120 has a structure in which a nozzle plate 51P, a flow path plate 52P, a diaphragm 56, and the like are laminated and joined.
  • the nozzle plate 51P constitutes the nozzle surface 50A of the line head 120, and a plurality of nozzles 51 communicating with the respective pressure chambers 52 are two-dimensionally formed.
  • the nozzles adjacent to the nozzle 51-13 indicate the nozzle 51-12 and the nozzle 51-14.
  • the adjacent nozzle refers to a nozzle that ejects ink droplets at positions adjacent in the main scanning direction.
  • the abnormal nozzle information stored in the abnormal nozzle storage unit 20 is acquired by the abnormal nozzle detection unit 22.
  • the abnormal nozzle refers to a non-ejection nozzle or a flying bent nozzle.
  • An abnormal nozzle is a nozzle that produces a defect such as non-ejection or ejection bending, and is a nozzle that does not eject ink normally.
  • the pixel row aligned in the paper conveyance direction corresponding to the abnormal nozzle is the region A (first pixel row), and the pixel row adjacent to the region A (the pixel row on both sides of the region A) is the region B (second pixel row).
  • a pixel column adjacent to the side opposite to the region A of the region B is a region C (third pixel column), and a region not corresponding to any of the regions A, B, and C is a region D (fourth Pixel column).
  • FIG. 13 is a diagram showing the generation ratio of large droplets, medium droplets, and small droplets with respect to the amount of ejected ink for each region.
  • 13A shows the generation ratio of each drop in the area D
  • FIG. 13B shows the generation ratio of each drop in the area C
  • FIG. 13C shows the generation ratio of each drop in the area B.
  • the ratio of each droplet generation to the amount of ink to be output is set so that the characteristics are different for each region.
  • the density measurement test chart 60 is formed in one scan by ejecting ink from all the nozzles of the line head 120 onto the paper P transported in the paper transport direction. Therefore, the length of each density patch in the direction orthogonal to the paper conveyance direction is equal to the width of the nozzle row.

Abstract

La présente invention concerne un dispositif, un procédé et un programme de traitement d'image ainsi qu'un dispositif d'enregistrement à jet d'encre destinés à réduire la visibilité de bandes associées à des parties de buses défectueuses dans toutes les gradations. Selon l'invention, le dispositif, le procédé et le programme de traitement d'image ainsi que le dispositif d'enregistrement à jet d'encre divisent des données d'image en zones d'une première rangée de pixels, dans une première direction qui correspond à une buse défectueuse, d'une deuxième rangée de pixels adjacente à la première rangée de pixels, d'une troisième rangée de pixels adjacente à la deuxième rangée de pixels et d'une quatrième autre rangée de pixels. Lorsque des ensembles de données de sortie sont créés, lesquels présentent des rapports d'occurrence différents de gouttelettes d'encre relativement grosses, des rapports différents d'occurrence de gouttelettes d'encre relativement petites, et des quantités différentes d'encre déchargées par unité de surface conformément aux valeurs de gradation de données d'image de chacune des zones divisées, des ensembles de données de sortie qui diffèrent entre des cas de première valeur de gradation relativement élevée et des cas de première valeur de gradation relativement faible sont créés pour des troisièmes buses qui correspondent à la première rangée de pixels.
